"And obviously on our "shh" finger," Lucy pointed out in her post, a reference to the series' opening sequence. See the group's biggest "ssshhh" to date, showcasing their tiny new bits of ink, here.

Pretty Little Liars began its long, winding, creepy doll-filled, occasionally confusing but always riveting journey in 2010, and six years later the cast and crew bid an emotional goodbye to the Freeform series as they wrapped their last-ever scenes on set.

"This just feels weird," show creator I. Marlene King tweeted on October 26, with the hashtags #PLLSeriesFinale and#PLLlastdayfilming. She also shared a group shot of Rosewood's most tormented pals after Keegan Allen's last-ever scene playing Toby Cavanaugh on Tuesday, writing "that was a tough one."

Allen echoed King's nostalgia on Twitter in a flurry of posts. He also wrote a heartfelt Instagram note to co-star Troian Bellisario, who plays brainy Liar Spencer, with a photo of the actress playing an acoustic guitar.

“In these last hours embodying our characters, I want to reflect on a great love I have for you. Last night, I was very present and took the time to really look at you as you are now," Allen wrote. "I have grown up with you and learned so much from you. I’m a better person because of you. I will continue to look up to you as an actor, because you care so deeply for our craft, and bring the greatest truth to everything you do. I absolutely love you Troian Bellisario."

Troian also shared a message from her real-life fiance, Suits star Patrick Adams, who wrote a goodbye email to her character Spencer Hastings. She added, "I had no idea how hard this would be."

"I want to wish you and Aria and Emily and Hannah (and Hardy) a little piece and quiet wherever you head from here. May there be less corpses, text messages, doll houses, mind games, tears and disappeared loved ones wherever it is you end up," Adams wrote to Spencer in his note. Agreed.
